What’s inside

Low disclosure
Ingredient Transparency · database check
Low

Most active ingredients don't disclose an individual amount — you can't tell how much of each you're getting.

Why this rating?
  • The label discloses an exact amount for 0 of its 7 active ingredients.
  • “Proprietary Extract Blend” is a proprietary blend — the label gives one combined amount (1,960 mg) without saying how much of each component you get.

Reintegrate contains seven active ingredients. Cocoa bean seed extract, valerian root extract, reishi fruiting body extract, silk tree bark extract, kanna aerial parts extract, and passionflower aerial parts extract (fresh) are the named ones; there's also a proprietary blend whose specific components are listed separately on the label.

The product is delivered as a liquid in water, organic cane alcohol, and glycerin.

Does it work?

Moderate evidence
Evidence for Intended Use · database check
By FDA rules, dietary supplements can’t claim to treat, cure, or prevent disease — so labels speak in careful marketing language. We discern each product’s intended use from its name, label claims, and label statements, then grade the clinical evidence for that use. How these ratings are computed
Moderate

Some clinical evidence supports this product's ingredients for its stated purpose, but it isn't conclusive.

Why this rating?
  • The label markets this product for: Nervous system support.
  • We looked for evidence on: Anxiety, Stress, Insomnia, Depression, Restless legs syndrome (RLS), Psychological well-being — and 4 related terms.
  • The strongest evidence on file: Valerian is rated "Possibly Effective" for Insomnia (Natural Medicines).
  • Also on file: Passion Flower is rated "Possibly Effective" for Pre-procedural anxiety, Insomnia.
  • Also on file: Valerian is rated "Insufficient Reliable Evidence To Rate" for Pre-procedural anxiety, Depression, Restless legs syndrome (RLS), Stress.

The evidence is mixed and mostly modest. Cocoa bean is possibly effective for cardiovascular disease but possibly ineffective for stretch marks; evidence isn't established for aging skin, HIV-related cholesterol issues, or asthma.

Valerian root is possibly effective for insomnia but we don't have reliable evidence for restless legs, anxiety before procedures, or stress. Reishi mushroom is possibly ineffective for high cholesterol and lacks established evidence for altitude sickness, Alzheimer's disease, or athletic performance.

Passionflower is possibly effective for insomnia and anxiety before medical procedures. For kanna and silk tree bark, the data we hold shows no effectiveness ratings.

This product was not formulated with a single, well-established use — it's a blend meant to address several concerns, but the evidence for most of them is either absent or suggests only modest benefit.

How safe is it?

Well-documented data
Safety Information · database check
Well characterized

Adverse-effect, pregnancy, and general safety data are on file for most of these ingredients.

Why this rating?
  • We hold adverse-effect (side-effect) data for 5 of the 6 matched ingredients.
  • Pregnancy & breastfeeding safety ratings cover 6 of 6.
  • General safety write-ups exist for 6 of 6.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Most ingredients are generally well tolerated short-term, though long-term safety isn't well studied for valerian, reishi, or kanna. Cocoa's common side effects are stomach upset, nausea, constipation, headache, and diuresis (increased urination); rare serious effects include a rapid heartbeat.

Valerian may cause drowsiness, dizziness, mental slowness, headache, or vivid dreams; if you stop it abruptly after long use, you may experience withdrawal symptoms like anxiety and insomnia — taper slowly. Reishi commonly causes dizziness, dry mouth, itching, nausea, rash, or stomach upset; respiratory allergy to reishi spores can occur.

Kanna and passionflower may cause drowsiness; kanna's reported side effects include anxiety, headache, insomnia, and nausea. Passionflower is well tolerated but can cause confusion, dizziness, and sedation; one case report involved severe nausea, vomiting, and heart rhythm changes at very high doses.

Silk tree bark has limited human safety data. For pregnancy: safety data are not established for valerian, reishi, kanna, passionflower, or silk tree bark — avoid them or talk with your doctor or pharmacist.

For breastfeeding: cocoa's caffeine passes into breast milk and can make your baby fussy — keep intake modest; valerian, reishi, kanna, passionflower, and silk tree bark all lack sufficient safety data — consult your healthcare provider.

Meds to double-check

Moderate interaction found
Known Interaction Concern · database check
Moderate identified

The most serious documented interaction for these ingredients is Moderate. Check your medications for a personalized result.

Why this rating?
  • 6 of the 6 matched ingredients can interact with medications — Cocoa, Valerian, Passion Flower, Reishi Mushroom, Sceletium, among others.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: anticoagulant / antiplatelet drugs; diabetes medications; lithium.
  • For scale: 1,318 individual medications appear in the full list. A big number alone doesn't make a product dangerous — what matters is whether YOUR medication is on it, so run yours through the interaction checker on this page.

If you take ephedrine or any stimulant medication, check with your pharmacist before using this product — cocoa's caffeine may cause serious heart and blood pressure effects. Also double-check if you're on blood pressure medications (antihypertensive drugs), blood thinners or antiplatelet drugs, diabetes medications, sedatives or CNS depressants, benzodiazepines like alprazolam, quinolone antibiotics, or alcohol.

The combination of cocoa and valerian with these drugs carries Moderate-severity risks.

The bottom line

Scorecard at a glanceFormula with limited ingredient disclosure with some supporting evidence for its stated purpose. Moderate medication interactions have been identified, and safety information is well characterized.

This is a multi-ingredient herbal blend targeting relaxation and cardiovascular support, with modest evidence for some uses (insomnia, pre-procedure anxiety, heart health) and uncertain benefit for others. Because it contains stimulant-like compounds (caffeine from cocoa) and multiple sedating herbs, it's not right for everyone — especially anyone on blood pressure medications, sedatives, blood thinners, or stimulant drugs.

Talk with your pharmacist before you start, and don't add it to your routine without checking your medications against the interaction tool on this page.

Valerian Root Extract6 drug types · 902 drugs

Alcohol (Ethanol)

Valerian can have additive sedative effects when used concomitantly with alcohol.
Valerian has sedative effects. Theoretically, valerian might have an additive sedative effect when combined with alcohol. Excessive sedation has been reported in an alcohol-abusing individual who took valerian and Gingko biloba. However, the potential interaction between valerian and alcohol has been disputed in other research. Limited evidence suggests that a combination of valerian 160 mg and lemon balm 80 mg (Euvegal) does not cause further deterioration in reaction ability and reaction rate when taken with alcohol as compared to the effects of alcohol alone.

Likelihood Possible Evidence B
Alprazolam (Xanax)

Valerian can have additive sedative effects when used with alprazolam. Also, valerian in high doses might modestly increase alprazolam levels, though this is not likely to be clinically significant.
Valerian has sedative effects. Theoretically, valerian might cause additive sedation when combined with alprazolam. Also, a small pharmacokinetic study shows that taking valerian extract 1000 mg daily (providing 11 mg valerenic acid) might increase alprazolam levels by about 19%. This might be due to valerian's mild inhibition of cytochrome P450 3A4 (CYP3A4). Despite being statistically significant, this increase is not likely to be clinically significant.

Likelihood Possible Evidence B
Cns Depressants

Valerian can have additive sedative effects when used concomitantly with CNS depressant drugs.
Theoretically, concomitant use of valerian and drugs with sedative and anesthetic properties may cause additive therapeutic and adverse effects.

Likelihood Possible Evidence D
Glucuronidated Drugs

Valerian might weakly inhibit glucuronidation and increase concentrations of drugs metabolized by UGT1A1 and UGT2B7.
In vitro research shows that methanolic valerian extract and valerenic acid might competitively inhibit UDP-glucuronosyltransferase (UGT) 1A1 (UGT1A1) and UGT2B7.

Likelihood Possible Evidence D
Cytochrome P450 2D6 (Cyp2D6) Substrates

Valerian does not seem to have a clinically relevant effect on levels of drugs metabolized by CYP2D6.
Although some in vitro evidence suggests that valerian affects CYP2D6, clinical pharmacokinetic (PK) studies show that valerian is unlikely to affect the CYP2D6 enzyme. In one PK study, taking valerian 1000 mg (providing about 11 mg valerenic acid) nightly for 14 days did not affect the metabolism of dextromethorphan, a CYP2D6 substrate. In another PK study, taking valerian 125 mg three times daily for 28 days did not affect metabolism of debrisoquine, an accepted CYP2D6 probe-substrate.

Likelihood Unlikely Evidence B
Cytochrome P450 3A4 (Cyp3A4) Substrates

Valerian does not seem to have a clinically relevant effect on levels of drugs metabolized by CYP3A4.
Although some in vitro evidence suggests that valerian extract might inhibit or induce CYP3A4, clinical pharmacokinetic (PK) studies show that valerian does not have a clinically significant effect on the CYP3A4 enzyme. In one PK study, taking valerian 125 mg three times daily for 28 days did not affect metabolism of midazolam, an accepted CYP3A4 probe-substrate. In another PK study, taking valerian 1000 mg (providing about 11 mg valerenic acid) nightly for 14 days modestly increases levels of alprazolam, a CYP3A4 substrate, suggesting mild inhibition of CYP3A4. However, this mild inhibition is unlikely to be clinically relevant.

Likelihood Possible Evidence B
Valerian Root Extract full monograph & interactions

Passionflower Aerial Parts Extract, Fresh3 drug types · 836 drugs

Cns Depressants

Concomitant use of passion flower with sedative drugs might cause additive effects and side effects.
Research in animals and humans shows that passion flower has sedative effects which can be additive when used with sedative medications like lorazepam.

Likelihood Possible Evidence D
Cytochrome P450 3A4 (Cyp3A4) Substrates

Theoretically, passion flower might decrease the effects of CYP3A4 substrates.
In vitro research suggests that passion flower can induce CYP3A4 enzymes, albeit to a much lower degree than rifampin, a known CYP3A4 inducer.

Likelihood Possible Evidence D
Organic Anion-Transporting Polypeptide Substrates (Oatp)

Theoretically, passion flower might reduce the bioavailability of OATP2B1 and OATP1A2 substrates.
In vitro research shows that the passion flower constituents apigenin and vitexin inhibit OATP2B1 and OATP1A2. This inhibition may be dose-dependent. One specific high-flavonoid passion flower extract (Valverde) seems to inhibit OATP2B1 and OATP1A2, while another extract with a lower flavonoid concentration (Arkocaps) shows less potent inhibition. OATPs are responsible for the uptake of drugs and other compounds into the body; however, the specific activities of OATP2B1 and OATP1A2 are not well characterized.

Likelihood Possible Evidence D
Passionflower Aerial Parts Extract, Fresh full monograph & interactions

Cocoa Bean Seed Extract37 drug types · 661 drugs

Ace Inhibitors (Aceis)

Theoretically, taking cocoa with ACEIs might increase the risk of adverse effects.
Human research shows that dark chocolate can inhibit ACE. Additionally, prolonged angioedema in an elderly patient on an ACE inhibitor was precipitated with intake of diabetic chocolate.

Likelihood Possible Evidence D
Adenosine (Adenocard)

Theoretically, cocoa might decrease the vasodilatory effects of adenosine and interfere with its use prior to stress testing.
Cocoa contains caffeine. Caffeine is a competitive inhibitor of adenosine at the cellular level. However, caffeine does not seem to affect supplemental adenosine because high interstitial levels of adenosine overcome the antagonistic effects of caffeine. It is recommended that methylxanthines and methylxanthine-containing products be stopped 24 hours prior to pharmacological stress tests. However, methylxanthines appear more likely to interfere with dipyridamole than adenosine-induced stress testing.

Likelihood Possible Evidence B
Alcohol (Ethanol)

Theoretically, concomitant use might increase levels and adverse effects of caffeine.
Cocoa contains caffeine. Alcohol reduces caffeine metabolism. Concomitant use of alcohol can increase caffeine serum concentrations and the risk of caffeine adverse effects.

Likelihood Probable Evidence D
Anticoagulant/Antiplatelet Drugs

Theoretically, cocoa may increase the risk of bleeding if used with anticoagulant or antiplatelet drugs.
Clinical research shows that intake of cocoa can inhibit platelet adhesion, aggregation, and activity and increase aspirin-induced bleeding time. For patients on dual antiplatelet therapy, cocoa may enhance the inhibitory effect of clopidogrel, but not aspirin, on platelet aggregation.

Likelihood Possible Evidence D
Antihypertensive Drugs

Theoretically, taking cocoa with antihypertensive drugs might increase the risk of hypotension.
Clinical research shows that cocoa can modestly decrease blood pressure in hypertensive and normotensive patients.

Likelihood Possible Evidence D
Beta-Adrenergic Agonists

Theoretically, large amounts of cocoa might increase the cardiac inotropic effects of beta-agonists.
Cocoa contains caffeine. Theoretically, large amounts of caffeine might increase cardiac inotropic effects of beta-agonists. A case of atrial fibrillation associated with consumption of large quantities of chocolate in a patient with chronic albuterol inhalation abuse has also been reported.

Likelihood Probable Evidence D
Cytochrome P450 1A2 (Cyp1A2) Inhibitors

Theoretically, concomitant use might increase the levels and adverse effects of caffeine.
Cocoa contains caffeine. Caffeine is metabolized by cytochrome P450 1A2 (CYP1A2),. Theoretically, drugs that inhibit CYP1A2 may decrease the clearance rate of caffeine from cocoa and increase caffeine levels.

Likelihood Possible Evidence D
Dipyridamole (Persantine)

Theoretically, cocoa might decrease the vasodilatory effects of dipyridamole and interfere with its use prior to stress testing.
Cocoa contains caffeine. Caffeine may inhibit dipyridamole-induced vasodilation. It is recommended that methylxanthines and methylxanthine-containing products be stopped 24 hours prior to pharmacological stress tests. Methylxanthines appear more likely to interfere with dipyridamole than adenosine-induced stress testing.

Likelihood Probable Evidence B
Disulfiram (Antabuse)

Theoretically, disulfiram might increase the risk of adverse effects from caffeine.
Cocoa contains caffeine. In human research, disulfiram decreases the rate of caffeine clearance.

Likelihood Probable Evidence B
Diuretic Drugs

Theoretically, using cocoa with diuretic drugs might increase the risk of hypokalemia.
Cocoa contains caffeine. In excessive amounts, caffeine can reduce potassium levels due to stimulation of the sodium-potassium pump. Diuretics can also cause lower potassium levels.

Likelihood Possible Evidence D
Ephedrine

Theoretically, concomitant use might increase the risk for stimulant adverse effects.
Cocoa contains caffeine. There is evidence that using ephedrine with caffeine might increase the risk of serious life-threatening or debilitating adverse effects such as hypertension, myocardial infarction, stroke, seizures, and death.

Likelihood Possible Evidence D
Estrogens

Theoretically, estrogens might increase the levels and adverse effects of caffeine.
Cocoa contains caffeine. Estrogen inhibits caffeine metabolism.

Likelihood Probable Evidence B
Flutamide (Eulexin)

Theoretically, cocoa might increase the levels and adverse effects of flutamide.
Cocoa contains caffeine. In vitro evidence suggests that caffeine can inhibit the metabolism of flutamide.

Likelihood Possible Evidence D
Fluvoxamine (Luvox)

Theoretically, fluvoxamine might increase the levels and adverse effects of caffeine.
Cocoa contains caffeine. Fluvoxamine reduces caffeine metabolism.

Likelihood Probable Evidence D
Lithium

Theoretically, abrupt cocoa withdrawal might increase the levels and adverse effects of lithium.
Cocoa contains caffeine. There are two case reports of lithium tremor that worsened upon abrupt coffee withdrawal.

Likelihood Possible Evidence D
Monoamine Oxidase Inhibitors (Maois)

Theoretically, concomitant use might increase the risk of a hypertensive crisis.
Cocoa contains caffeine. Large amounts of caffeine with MAOIs might precipitate a hypertensive crisis.

Likelihood Possible Evidence D
Nicotine

Theoretically, concomitant use might increase the risk of hypertension.
Cocoa contains caffeine. Concomitant use of caffeine and nicotine has been shown to have additive cardiovascular effects, including increased heart rate and blood pressure. Blood pressure was increased by 10.8/12.4 mmHg when the agents were used concomitantly.

Likelihood Probable Evidence B
Pentobarbital (Nembutal)

Theoretically, cocoa might decrease the effects of pentobarbital.
Cocoa contains caffeine. Caffeine might negate the hypnotic effects of pentobarbital.

Likelihood Possible Evidence B
Phenobarbital (Luminal)

Theoretically, cocoa might reduce the effects of phenobarbital and increase the risk for convulsions.
Cocoa contains caffeine. Animal research suggests that caffeine can decrease the anticonvulsant activity of phenobarbital. The exact mechanism of this interaction is unclear.

Likelihood Possible Evidence D
Phenylpropanolamine

Theoretically, phenylpropanolamine might increase the risk of hypertension, as well as the levels and adverse effects of caffeine.
Cocoa contains caffeine. Concomitant use of phenylpropanolamine and caffeine might cause an additive increase in blood pressure. Phenylpropanolamine also seems to increase caffeine serum levels.

Likelihood Probable Evidence B
Phenytoin (Dilantin)

Theoretically, cocoa might reduce the effects of phenytoin and increase the risk for convulsions.
Cocoa contains caffeine. Animal research suggests that caffeine can decrease the anticonvulsant activity of phenytoin. The effect does not seem to be related to the seizure threshold-lowering effects of caffeine. However, the exact mechanism of this interaction is unclear.

Likelihood Possible Evidence D
Quinolone Antibiotics

Theoretically, quinolone antibiotics might increase the levels and adverse effects of caffeine.
Cocoa contains caffeine. Quinolones (also referred to as fluoroquinolones) decrease caffeine clearance.

Likelihood Probable Evidence B
Riluzole (Rilutek)

Theoretically, concomitant use might increase the levels and adverse effects of both caffeine and riluzole.
Cocoa contains caffeine. Caffeine and riluzole are both metabolized by cytochrome P450 1A2, and concomitant use might reduce metabolism of one or both agents.

Likelihood Possible Evidence D
Stimulant Drugs

Theoretically, concomitant use might increase stimulant adverse effects.
Cocoa contains caffeine. Concomitant use might increase the risk of stimulant adverse effects.

Likelihood Probable Evidence C
Theophylline

Theoretically, cocoa might increase the levels and adverse effects of theophylline.
Cocoa contains caffeine. Large amounts of caffeine might inhibit theophylline metabolism. Caffeine decreases theophylline clearance 23% to 29%.

Likelihood Probable Evidence B
Cocoa Bean Seed Extract full monograph & all 37 interactions

Reishi Fruiting Body Extract 3 drug types · 375 drugs

Anticoagulant/Antiplatelet Drugs

Theoretically, high doses of reishi mushroom might increase the risk of bleeding.
A dose of 1.5 grams daily of reishi mushroom does not seem to decrease platelet aggregation, but a higher dose of 3 grams daily does.

Likelihood Possible Evidence D
Antidiabetes Drugs

Theoretically, reishi mushroom might have additive effects with antidiabetes drugs.
Animal research suggests that reishi mushroom decreases blood sugar. However, in patients with type 2 diabetes, taking reishi mushroom does not reduce fasting glucose levels, and its effects on glycated hemoglobin are inconsistent.

Likelihood Possible Evidence D
Antihypertensive Drugs

Theoretically, concurrent use of reishi mushroom with antihypertensive drugs might increase the risk of hypotension.
Reishi mushroom has shown hypotensive activity in animal research. Clinical evidence suggests that reishi mushroom reduces blood pressure in some, but not all, patients with hypertension.

Reintegrate by Five Flavors Herbs: Common Questions

Does Reintegrate by Five Flavors Herbs interact with any medications?
Yes. Based on its ingredients, Reintegrate has a known interaction with 1,317 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Reintegrate contains 7 active ingredients, and an interaction can come from any of them. We check every ingredient, combine the results into one list per medication, and show which ingredient and mechanism is responsible.
Where does this information come from?
The product label data comes from the NIH Dietary Supplement Label Database (DSLD); the interaction data is built on the Natural Medicines database and reviewed by HelloPharmacist pharmacists.
Does this product have caffeine?
Yes. The cocoa bean extract in Reintegrate contains caffeine. If you're sensitive to caffeine or take medications that interact with it (like ephedrine, quinolone antibiotics, or certain blood pressure drugs), you need to check with your pharmacist before using this product.
Will this make me drowsy?
It may. Valerian, passionflower, silk tree bark, and kanna all have sedative properties, so drowsiness, dizziness, and mental slowness are possible — especially if you take it regularly or in larger doses. Don't drive or operate machinery until you know how it affects you.
Is it safe to use while pregnant or breastfeeding?
Safety data aren't established for most of the herbs in this blend during pregnancy or breastfeeding. Talk with your doctor or pharmacist about whether it's right for you — they can weigh the risks and benefits for your situation. If you're breastfeeding and choose to use it, keep in mind that cocoa's caffeine does pass into breast milk and may make your baby fussy.
Can I use this if I take blood pressure medication?
Possibly, but you need to check first. Both cocoa and reishi can lower blood pressure, so taking them with antihypertensive drugs may increase the risk of blood pressure dropping too low. Your pharmacist can review your specific medication and dosage.
What if I'm on a blood thinner or blood clot preventer?
Reishi mushroom may increase bleeding risk at higher doses, so you should not start this product without running it past your pharmacist if you take anticoagulants or antiplatelet drugs like warfarin or aspirin.
Can I stop taking valerian suddenly if I've been using it for a while?
No — if you've been taking valerian in this product regularly for weeks or longer, taper it slowly rather than stopping at once. Abrupt cessation can cause withdrawal symptoms like anxiety, insomnia, irritability, and in rare cases heart rhythm changes. Gradually reduce your dose over a few days or a week.
